Application filed August 16, 1910. Serial No. 577,464.

Chicago, in the county of Cook andfitate 0t.-

lllinois, have invented a new and uset'nllmprovement in Retainers forBall and Roller Bearings, of which the following is a coin; pletespecification.

The main objects of this invention are to provide a retainer forhearings in which either balls or rollers may be employed withoutchanging or altering the construction; toprovide a retainer foreitherball or roller bearings which is of very cheap and simpleconstruction and not liable to get out of repair; and to provide aretainer iii which the spacers are so formed that theywill carry eitherballs or rollers of the same diameter, and'perinit the removal orinsertion otthe balls or rollers without injuring or destroying theretainer.

A. specific construction embodied in said invention is illustrated inthe accompanying drawings, in which:

liliguge 1 is a fragmentary, side elevation of tl retainer with theparts assembled but beforedhe spacer plates are curved or dished andsecured in place. Fig. 2 is a fragi'nentary, sidaelevation of theretainer with the spacer plates dished and partly secured in place, andwith balls between the spacers. Fig. 3 is a plan view ol theconstruction shown in Fig. 1.- Fig. l is aplan view of the constructionshown in Fig. 2. Fig. 5 is a fragmentary, plan view of the retainer withrollers therein.

I n the construction shown, there' are two annular retaining members orrings 1 and 2, which are-flattened in planes transversely of their axes,and each is provided at regular intervals with apertures 3 whichregister 7 with like apertures in the other ring and in which thespacers are secured.

Each spacer comprises a pair of oppositely facing" spacer plates 4, andthere is a pair of plates so cured in each pair of. registeringapertures 3-in said rings, or in other words there is a i pair of spacerplates between each two adj acent balls or rollers. Each spacer platec0mprises a flat strip of metal of a width approximately equal to thewidth of the rings 1 and 2 and of'a length to fit between the rings andhold them'. the desired distance apart. On each end of each plate 45 isa lug 5, which lugs are adapted to extend through the apertures 3 and tobe bent laterally on the outer sides of the rings to hold fthe plates inplace. Preferably the-lugs of each plate are bent oppositely from thoseof the other plate of the same spacer. Said plates set in planescoinciding with the radii of the rings, so that their inner edges 6 arecloser together than their outer edges, and In'evcnt the balls 7 orrollers 8 from passing tlitlOlJcUVQOl], Wllllc pcrmittii'ig said ballsor rollers to enter between the outer edges and liev in the intersticesor pockets between the spacers. Each spacer plate l has its corners9.t-1.|rned in 'ardly toward the adjacent ball or roller, so that thoplate'is dished orcup shaped on its face adjacent to the ball or roller.

From the foregoing description it will be seen that each spacercomprises a pair of.

rality oi. registering a mrtures therein, 9. p111- rality of pairs ofspacer plates between said rings, andthe plates of each pair havingtheir corners turned oppositcly,xand lugs on theends of said platesadapted to be socured in said apertures.

ln testimony whereof I have hereunto subscribed my name in the presenceof two witnesses.
